HESI Fundamentals Practice Questions

Correct Answer: B

Rationale: A peak flow meter is used to measure forced expiratory volume, which helps in monitoring asthma. This measurement provides valuable information about how well the client's lungs are functioning and how narrow their airways are. Choice A is incorrect because determining oxygen saturation is typically done using a pulse oximeter. Choice C is incorrect as a peak flow meter is not used to monitor the atmosphere for allergens but rather to assess lung function. Choice D is incorrect as providing metered doses for inhaled bronchodilators is the function of a metered-dose inhaler, not a peak flow meter.

Correct Answer: B

Rationale: The correct answer is B: 'Changing the patient's position.' Repositioning the patient involves physically moving and adjusting their position in bed, which is a task that can be safely delegated to nursing assistive personnel (NAP). This task does not require clinical judgment or assessment skills beyond the ability to follow guidelines for proper positioning. Choices A, C, and D involve assessments or judgments that require a higher level of training and knowledge, making them more appropriate for a nurse to perform. Choice A involves assessing comfort, which may involve subjective factors and individual preferences. Choice C involves identifying hazards related to immobility, which requires understanding the potential risks and complications associated with immobility. Choice D involves assessing circulation, which requires a higher level of clinical knowledge and understanding of circulatory issues.

Correct Answer: A

Rationale: The correct answer is to use tracheostomy covers when outdoors. This practice helps protect the stoma from foreign particles and temperature changes, reducing the risk of infection. Maintaining a sterile technique when performing tracheostomy care (choice B) is important to prevent infections but is not specific to outdoor care. Removing the outer cannula for routine cleaning (choice C) is not recommended as it may cause trauma or dislodgment of the tracheostomy tube. Cleaning around the stoma with povidone-iodine (choice D) is not advisable as it can be irritating to the skin and may impair the healing process.

Correct Answer: B

Rationale: In this scenario, the nurse is facing a critical situation with a client showing signs of hemorrhagic shock. The surgeon's directive of waiting for an hour without providing immediate intervention poses a risk to the client's well-being. The nurse should prioritize the client's safety and advocate for timely and appropriate care. Notifying the nursing manager is the correct action as it activates the chain of command to ensure that the client receives the necessary care promptly. Documenting the provider's directive, consulting the risk manager, or completing an incident report are not the immediate actions needed to address the client's deteriorating condition and ensure patient safety.

Correct Answer: D

Rationale: The inner forearm is the most appropriate site for administering a tuberculin skin test. This test requires an intradermal injection, which is administered just below the surface of the skin. The inner forearm provides a flat, easily accessible surface for this type of injection. Choices A, B, and C are incorrect because the tuberculin skin test should not be administered into a muscle (deltoid muscle or vastus lateralis muscle) or into the abdomen. The test requires precise placement within the dermal layer of the skin on the inner forearm to accurately assess for a reaction.
